Design of Weldments

Approximately forty years ago welded steel design was first applied to a mass-produced product, electric motors. The result of this application was a 50% weight and cost reduction. Since that time welded steel design has gradually and continuously expanded its usefulness into all types of products with comparable results in economy and improvement. This long and practical experience has created a fund of knowledge which has never been accumulated in one publication and made available to designers ans engineers. Much of it has never been published in any for,, remaining in the heads and hands of the practitioners of this science and art. The James F. Lincoln Arc Welding Foundation crated in 1935 by the Lincoln Electric Company to help advance this progress in welded design, has been fortunate in having has access to much of this information through its various award programs and educational activities. The Foundation, believing this knowledge is now of broad general interest, publishes this manual to make this information available to designers and engineers for their use in make the decisions they face in applying welded design.
